Headphone Output Short-Circuit Detection
Note2: Loudspeaker short-circuit protection is effective only when LC or ferrite bead filters are properly used.
Long time short circuit will reduce device reliability. AD82551A protects itself from short-circuit
damage only when the lines connected to loudspeakers are shorted to each other or to GND.
AD82551A will be burnt if the lines connected to loudspeakers are shorted to VDDL(VDDR).
